public class ImageIcon
extends AbstractImage

The ImageIcon class provides an component that displays an ImageReference. A height and width value can be specified to overide what may be defined in the ImageReference itself. This allows images to be "scaled" to different dimensions.

The advantage of ImageIcon over using a Label is that you can scale ImageReference objects that you may not know the dimensions of, and it can be clicked on like a Button.

The following code shows sample usage of this component.

   import echopoint.ImageIcon;

     ...
     final ImageIcon icon = new ImageIcon( "image/imagemap.gif" );
     icon.setWidth( 500 );
     icon.setHeight( 300 );
     icon.setActionCommand( "iconClicked" );
     icon.addActionListener( ... );

     final Column column = new Columnn();
     column.add( icon );
